Being a Ram "classic" owner and having a bunch of family, friends and co-workers with them, one thing to consider is, do the new style Rams have a different parking brake system?
Reason I ask is, if you live in rustier areas, you will have issues with the parking brake system on classic 1500s and it usually happens way earlier than it should. The actuator bits that run through the rear backing plates corrode and seize up. The usual tell-tale that you are starting to have a problem with it is P-brake cable sag. It can get bad enough that the shoes won't release. I know some guys that have had it fixed under warranty or out of pocket and it's a $1200+ dealer job.
My 2017 starting acting up months ago (after only 2 winters!) and I was able to manually free it up, but haven't used the P-brake since. I'll be doing brakes all the way around on it soon and I'm hoping to be able to free mine up 100% when I pull the rears apart.
This should be a non-issue for those who don't live in the rust belt.
For those that do, maybe working the P-brake several times per week could avoid this? I did exercise mine, but it wasn't weekly.
